It’ll also unlock ‘Siltbreaker’, a multiplayer campaign split into two parts.

The official site offers more details: “Available to play later this month—and with Act II arriving in July—this all-new campaign calls upon you to party up with three friends or queue-met allies to battle through a diverse landscape of loathsome monsters, cunning traps, and other lethal terrors.”

“With the fate of Dark Reef and the safety of the free seas hanging by a fish-gut thread, you’ll need to work together if you’re to find any hope for survival.”
